Deep crafting mechanics, two entire worlds full of secrets to discover, and thankfully gameplay far refined from the previous entry in the series. Very good game.

I have to say though, the random encounter rate really should have been toned down. It's not actually that high, but feels very high given how large and complex many of the rooms in the game are, and they keep interrupting your exploration making it hard to get your bearings. And this is coming from a guy who's been playing RPGs since the NES days!
